CR-11X charge sensitive preamplifier modules

Cremat's charge sensitive preamplifiers (CSPs) can be used to read out pulse signals from radiation detectors as diverse as semiconductor radiation detectors (e.g. CdTe, CZT), scintillator-photodiode detectors, gas-based detectors such as ionization chambers and proportional counters, and photomultiplier tubes (PMTs).

Cremat offers four different charge sensitive preamplifier modules: CR-110, CR-111, CR-112, and the CR-113. These preamplifiers are all modules of the same size and are pin-for-pin compatible with each other. They differ from each other primarily by their gain, with the CR-110 having the highest gain (1.4 volts per picoCoulomb). The CR-111 gain is approximately a factor of 10 reduced (0.13 volts per picoCoulomb). The gain of the CR-112 is a further factor of 10 reduced (13 mV per picoCoulomb), and the least sensitive preamplifier is the CR-113 (1.3mV per picoCoulomb). The CR-112 and CR-113 may be suitable for use with detectors producing large signals such as PMTs or SiPMs.

For information on choosing the best preamplifier module for your application, see our Tips on choosing a preamplifier page. Users seeking more information on the how to best implement these preamplifiers should see our CSP Application Notes. Specifications for our charge sensitive preamplifiers can be accessed from the following links:

Detect femtoJoule optical pulses

With a common pin photodiode, a low noise charge sensitive preamplifier and shaping amplifier, you can detect femtoJoule optical pulses. Here is a demonstration.

Why use charge sensitive preamplifiers?

Use a charge sensitive preamplifier (CSP) design to detect pulses with high precision and low noise.
